|This file documents the NCR53c400 extensions by Kevin Lentin and some
|enhancements to the NCR5380 core.
|This driver supports both NCR5380 and NCR53c400 cards in port or memory
|mapped modes. Currently this driver can only support one of those mapping
|modes at a time but it does support both of these chips at the same time.
|The next release of this driver will support port & memory mapped cards at
|the same time. It should be able to handle multiple different cards in the
|The drivers/scsi/Makefile has an override in it for the most common
|NCR53c400 card, the Trantor T130B in its default configuration:
| Port: 0x350
| IRQ : 5
|The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
|supported by the driver.
|If the default configuration does not work for you, you can use the kernel
|command lines (eg using the lilo append command):
|The driver does not probe for any addresses or ports other than those in
|the OVERRIDE or given to the kernel as above.
|This driver provides some information on what it has detected in
|/proc/scsi/g_NCR5380/x where x is the scsi card number as detected at boot
|time. More info to come in the future.
|When NCR53c400 support is compiled in, BIOS parameters will be returned by
|the driver (the raw 5380 driver does not and I don't plan to fiddle with
|This driver works as a module.
|When included as a module, parameters can be passed on the insmod/modprobe
| ncr_irq=xx the interrupt
| ncr_addr=xx the port or base address (for port or memory
| mapped, resp.)
| ncr_dma=xx the DMA
| ncr_5380=1 to set up for a NCR5380 board
| ncr_53c400=1 to set up for a NCR53C400 board
|modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1
| for a port mapped NCR5380 board or
|modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1
| for a memory mapped NCR53C400 board with interrupts disabled.
|(255 should be specified for no or DMA interrupt, 254 to autoprobe for an
| IRQ line if overridden on the command line.)
